Description

[Detailed explanation of the idea] The present invention relates to a seeding device.

In other words, it runs on two wheels while sliding the float on the rice field, and can sow seeds directly onto the rice field from each sowing device.In particular, the machine has good front-to-back balance and can run smoothly in a circle, while operating the steering wheel. The operator can monitor the sowing condition sufficiently and perform the sowing work without mistakes, and
To provide a seeding machine that can reliably sow seeds so that the planting depth is constant.

The embodiments shown in the drawings will be described below.

Figure 1 shows a plan view of the entire seeding machine, which is a submerged direct sowing machine, with two-wheeled double-wheeled wheels of 1°1 and axles 2.2.
The engine E is mounted on both sides of the rear of the mission case 3, and the engine E is directly connected to the front of the mission case 3, which is the frontmost part of the entire aircraft and in front of both axles 2, 2. 4a, a handle 4 that connects 4a,
4 is installed slightly higher at the rear of the fuselage.

A indicates the entire float, and the float A consists of a large main float a and both small auxiliary floats a1゜al,
The main float a is located between both axles 2 and 20 and is wide and long in the front-rear direction from below the engine E to below the base 4a of the nozzle 4, and both auxiliary floats a1. a1
is formed in a small size so as to be located on the rear and outer side of both axles 2, 2, and a compression spring 5 is interposed between the lower part of the mission case 3 on the front side of the axle 2 and the upper front part of the main float a. Configure.

In addition, drop ports 6 that penetrate vertically are formed at two places on the left and right at the rear of the main flow (a) and at the rear of the auxiliary floats a1 and al, and at the lower front part of each drop port 6, the bottom surface 7 of each float is formed. A groove portion 8 is formed that protrudes further downward, has a certain width, and is slightly longer in the front-rear direction.
The whole is made of resin and molded in one piece.

A fulcrum pin 10 is extended rearward from the base 4a of the handles 4, 4 and on the lower side of the handles 4, 4a, and is fastened to the upper surface near the rear of the main float a. The upper part of the support frame 12 fixed by the attachment 11 is rotatably fitted to the fulcrum pin 10, and the support frame 12 is fixed.
A connecting frame 13 can be freely inserted into both end portions 12a, 12a extending to both sides of the
and both auxiliary floats a1. Pin 1 connects the fixed frame 15 on the upper surface side of a1 and the end of each connecting frame 13.
6, the supporting pin 10 is sandwiched between balance springs 17, 17 on both sides, and both auxiliary floats a1. Balance springs 18, 18 are also connected to each other on a1.

B is a sowing machine, and there are four sowing machines B arranged at equal intervals in the horizontal direction, two on the rear of the main float a, and two on the rear of the main float a, and both auxiliary floats a1. a1
Attach each sowing machine B one by one and fix it so that each sowing machine B is located behind the axle 2 and in front of the rear of the handle 4, and fit the lower drop tube 19 of each sowing machine B into the drop opening 6 of each float. However, in each sowing device B, a roll 23 with four packets 22 arranged thereon is mounted on a shaft at the rear of the lower part of a homper 21 having an opening/closing lid 20 at the upper part, and the packets 22 transfer the seed rice 24 in the lower part of the homper 21. Scoop up the required number and drop into the drop tube 1.
Formed so that it can be released at 9.

The shaft 25 of the roll 23 in each sowing device B is extended outward, and the flexible transmission shaft 27 is attached to an engaging tool 26 fixed to the tip of the shaft 25.
The flexible transmission shaft 27 is detachably connected to the tip engaging portion 28 of
A support nut 30 at the tip of the outer 29 of the sowing device B can be removably screwed into a threaded portion 31 on the side of the sowing device B to form a connecting portion.

Further, a transmission section 3 is provided above the front part of the minsion case 3.
2, four transmission shafts 33 are provided protruding from the rear part of the transmission section 32, and the other end side of each flexible transmission shaft 27 connected to each sowing machine B is connected to each transmission shaft 33 at the connection section described above. Depending on the structure, they can be connected to each other in a detachable manner.

The seed rice 24 is made by coating sprouting rice with a mixture of lime peroxide and calcined stone, and can germinate even if it enters the soil.

By having the operator hold and operate the handles 4, 4, both wheels 1, 1 can be made to run on the rice field, and the float A slides on the rice field, but the left and right wheels 1, 1
Even if the machine tilts laterally due to unevenness of the tiller, the support frame 12 rotates around the fulcrum pin 10 and the pin 16.1
6 and each balance spring 17, 17, 18, 18, the main float a and both auxiliary floats a1. a
1 can always slide in a normal position without tilting against the rice field.

Grooves 8 on the bottom of each float form grooves on the rice field, and in each sowing device B, each packet 22 rotated by each flexible transmission shaft 27 collects the seed rice at the bottom of the hopper 21, as shown in FIG. While scooping up the required number of 24, rotate as it is and release it into the drop tube 19.
The seed rice 24 falling from the inside to the lower part of the drop opening 6 falls into the circular groove, so that seeding can be carried out at constant intervals according to the intervals at which the packets 22 are discharged.

In that case, each float maintains its normal posture with respect to the rice field as described above, so the planting depth remains constant.

Therefore, it is possible to plant 4 rows, but St. Pol) 14
．． 14 and remove both connecting frames 13, 13 and both flexible transmission shafts 27, 27, both auxiliary floats a1. a1
Also, both seeders B and B can be removed, and two rows can be planted using the two seeders B and H on the remaining main float a, and this structure can be adapted to on-road driving and storage.

In this way, the present invention installs an engine in front of a two-wheeled axle and a handle behind it, and pivots a float that slides on a circular surface below the handle so that it can rotate around a fulcrum pin. A plurality of seeding devices are attached to the rear part of the float which is behind the axle and in front of the rear part of the nodule, and a groove forming part is installed in the lower front part of the drop opening below the seeding device in the float, It runs on two wheels while sliding the float on the rice field, allowing seeds to be sown directly onto the rice field from each sowing machine.In particular, the front diameter of the machine is well balanced.
In addition, the float slide allows for smooth running on the rice field.
While operating the handle, the operator can fully monitor multiple seeding conditions right in front of them, allowing for error-free seeding work.Since the float can rotate around the fulcrum pin, the float can always maintain its normal posture, making it easier to plant. It has the characteristics that it is possible to reliably sow seeds at a constant depth and also to perform furrow boxwood well.
